Once the existence of Higgs Boson is known, there will be further work to prove its properties and understand the origins of the universe.
Dr Heuer said: "If the Large Hadron Collider continues to work I know we have enough collisions to produce enough signals to identify the Higgs Boson.
“We will know by the end of this year whether it exists or whether it is non-existent. This would be a huge discovery that after 50 years we are able to describe the visible universe.
"We will have taken a big step forward about our knowledge of the physical world. It will help us to understand the creation of the universe."
CERN require a high level of proof and will only announce that the Higgs Boson exists when there is just a one in three million chance they are wrong.
Dr Heuer said the discovery of the Higgs Boson will also help investigations into this wider universe. The visible universe only makes up 5 per cent and the rest is ‘dark energy’ and ‘dark matter’.
He said it was impossible to imagine at this stage how the knowledge of the particle could be applied to practical applications but pointed to previous discoveries have led to developments in medicine and the internet.
“Whatever basic science resolves, at some stage it is of use to society. The problem is we do not know when or where.”
The search for the God Particle has proved controversial. Critics feared the Large Hadron Collider could create a massive black hole that would "swallow the Earth".
Religious groups have also questioned the search for a particle at the origins of the universe.
Dr Heuer admitted that "micro black holes" may be created in the Large Hadron Collider but he insisted this was safe as they would decay almost immediately and it could even be good for science as it shows that micro black holes are occurring all the time.
He has had meetings with the Pope and insisted that the interface where science ends and religion or philosophy begins is changing all the time.
